MOTOR-WHEEL FOR VEHICLES.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed July 26,1905. Serial No. 271,303.

To rr// 1r/1 UIII/ if 111.114 con/x1771..- Be it known that I, WAnnnx-W. ANNABLE, l a citizen of the United States, residing at l GrandRapids, in the county of Kent and I State of Michigan, have. inventedcertain new 1 and useful Improvements in Motor-\Vheels lor Vehicles; andI. do hereby declare the loli lowing to be a full, clear, and exactdescrip- 1 tion of the invention, such as will enable 1 others skilledin the art to which "it apperl ta-ins to make and use the same. I Myinvention relates to improvements in i motor-wheels for vehicles, andmore particut larly to elcctrically-propelled wheels having 5 the motorwithin the wheel; and its object is i to provide the same with variousnew and '1 useful features hereinafter more fully de-l scribed, andparticularly pointed out in the 5 claims, reference beinghad to theaccompanyi ing drawings, in which-- Figure l is an elevation ol' a wheelwith the outer web and the motor removed to show the gearing; Fig. 2, avertical section of the device entire, taken on the line 2 2 of Fig. I.

Like mnnbers refer to like parts in both of l represents the axle, onwhich the wheel is rotat ive. 'lhe wheel provided with a conea n orrecessed inner web, 2 journaled on the axle and having a rim providedwith a tire 3, i prctcrably meumatic.

4 is a concave outer web to thewheel, detachably secured to the rim bybolts or screws i 5 and journaled on the outer end of the axle. 1 'lhcsewebs 2 and 1 torm a closed chamber within which the gearing and motorare arranged, the wheel-bmrrings being spaced apart and rotative on theaxle l. Secured between the peripheries of these webs and clamped by thebolts 5 is an internal gear (3, l which is the driven. gear ol' theseries and operates the wheel. tminecting this gear, with adriving-pinion N are two opposing; plant-.t-getus 7. Attached to thegears T and 1 rotativc therewith are pinions l2, whi h pin- 1 ,I'EISengage a stationary internal gear 12-3, the v. ch 4 of which gear isfixed upon the axle l a cent to the inner hearing ot' the wheel. b n;gears 7 and 12 are iournaled on studs It), supported in the oppositeends of a yoke. ll, rotaiiw on the. outside oi a sleeve 9, which sleeveis also rotative on the axle 1. The driving. .-ar o and the rotativemember of l the hgures. r l

, of a Grannne-ring armature 17, mounted on a spider 18, keyed to thesleeve 9 to rotate the same, and held-magnets 15 to rotate the armature,which magnets are supported by arms 16, iixed to the axle adjacent tothe outer bearing of the wheel. 1

Within the spider 18 is a commutator 1t), and on the arms 16 are mountedbrushes The electrical conductors and coils are not shown. Said.-.onductors are extended through openings 21 in the axle and arms andconnect with the brushes. In operation the attraction of thelieldm'iagnets rotates the armature, which in turn rotates the sleeveand drives the pinion S. This pinion rotates the planet-gears 7, whichin turn 2 drive the internal gear 6, which operates the wheel.

To provide su'ilicicnt speed of the motor I provide the pinions 12,which traverse the iixed internal gear 1.3 in a direction opposite tothe direction ol rotation of the gear 6, and thus subtract a portion ofthe forward movement of the gear (3, depending upon the proportions ofthe pinions l2 and gear 13. I. can thus also vary the ratio of speedbetween the motor and wheel by changing these pinions 12 and gear 13.The larger they are the greater the diIl'erence in speed, and thesmaller they are the less said dillerence will be. By this constructionI. can also gain access to all the mechanism within the wheel or removethe same as occasion requires without taking the wheel proper oil. thevehicle, the. rim and inner web serving to support the vehicle when allelse has been detached trom the axle and removed. The sleeve and yokeboth rotate in the same direction, thus reducing the friction, and thegear 13 serves as a lixed t'ulc'rum near the rim oi the wheel,

to which rim the power is applied by a large internal gear close tosame. ill tlnisrreduce the strains, 'l'riction, and risk ot'zlweakageoi" the parts.

Having thus fully described my invention,

5 what I claim, and desire to secure bylietters Patent, is

1. The combination ol" an inner concave web having an axial bearing, awheel-rim integral therewith, an outer concave web hav .journalcd. onthe ing an axial bearing, bolts to connect the peripheries of the webs,clamped between the and held thereby, a driving-pinion, gears connectingthe driving-pinion and the internal geanand a rotative motor memberconneeted to the pinion.

- 2. The combination of a non-rotative axle, an. inner Web j ournaled.on the axle, a Wheelrim on the Web, an outer web detachably secured tothe inner Web near the periphery and journaled on the axle, an internalgear between the outer portions of the webs and held thereby, a sleeverotative on the axle, a. rotative motor member and driving-pinionattached to the sleeve, and gears connecting the driving-pinion and theinternal gear.

3. The combination of a non-rotative axle, a wheel journaled on theaxle, an internal gear attached to the wheel, a gear fixed on the axle,a driving-pinion rotative on the axle, a rotative motor memberconi'iected to the pinion, a planet-gear connecting the pinion and theinternal gear onthe wheel, a pin ion attached to the planet-gear andengaging the fixed gear tLDdjllOttIlS for movably sup porting the axisof the planet-gear and oi the pnnon.
